The climat and the warmest clothes items needed

Hello everyone!
I am thinking of moving to RAK for work and I understand that climate is really warm there but still in winter time what is the lowest temperature and the warmest clothes you are wearing? Just to make right choise for the suitcase )
Any other tips on moving are really appreciated

if coming from the cool place to RAK in winter season then bring some black leather jackets, bcoze the temperature falls to below 10 degrees, don't forget to bring umbrella & monkey caps also.
